Notes

Some specimens of Chaetogaster diastrophus may have dorsal seatae; there is no need for the separation of such individuals under the name Pseudochaetogaster longmeri. Amphichaeta leydigii and A. americana are recorded and Homochaeta raptisae is transferred to this genus. The source of the confusion between Vejdovskyella comata and V. intermedia is identified and both are now accepted as valid species and are recorded from Washington and British Columbia, respectively. Vejdovskyella hellei is transferred to Specaria. The distinction between Nais communis and N. variabilis is documented, and the serrate nature of the hair setae of N. elinguis is newly described. Pristina idrensis is new to the Canadian fauna; P. aequiseta is new to British Columbia and Washington. The few remaining differences between our records and those presented by other workers are catalogued, yielding a total of 65 confirmed species and two probable additions to the North American fauna.
